I have an 80 inverted V that I would like to transform to something useful for 30m. It is fed with RG213 and a balun at the feedpoint. It is close to 3/4 wavelengths on each side which might be ok bu
The apex is at about 70ft so I can reach the ends without much difficulty. My high 80M dipole is fed with 160 ft or so of a good RG11, but even with that great coax, there's far too much loss in the
I was trying to avoid climbing. I have a SteppIR with the 30/40 so this would be an extra antenna for the 2nd radio. I tried researching a 1.5 wavelength dipole antenna on the internet but didn't fi
The further the better. If you put the 40 90 degrees off it will help. Otherwise you will have some interaction on 15 at 10 ft. I have the same arrangement. Look at turning the XM240 into a Moxon a

Have you taken everything out of the line and hooked the antenna directly to an analyzer or the rig? Make sure the tuner in the rig is off if you have one. Can you rotate the antenna, if so does the

HRO sells a stealth antenna wire. I used it for our RCV pennant at V3M. It is super lightweight. Multi-stranded. I suspect it would handle the 500 watts ok. I used a 40/80/160 antenna trapped an
Since the tape or wire inside moves it is 1/4 wave but there some band where you can select 3/4 wave I believe. There is a separate SteppIR group on Yahoo. I do not own a BigIR but have other Stepp
The XM240 uses a capacitor balun which get mixed reviews. I would use the current Balun that K9YC recommends. 8 turns or so around the proper clamp on ferrite material. The SWR should be much bette

Go slow especially if you are pulling smaller control lines you can burn the jacket or worse if there are bends, edges etc. Having someone feed the cable in would be nice too. If your are CERTAIN tha
